1 Li Bai: Yan, dream broken
2 "Ancient Meaning" was written by Chang Jian, a music poet in the Tang Dynasty. Among them, "Song and dance are in the blue clouds, and the flute is set off by boiling beads". The word "boiling" in poetic eyes is wonderful. It describes the flute sound with the boiling of water, which is novel and skillfully connects hearing with visual and tactile movements.
But the breeze stirred by butterfly wings is still rippling in the forest, with a faint fragrance of wood leaves. Suddenly, there is a flute sound-
Suddenly, there was silence in the forest, and even cicadas and birds suddenly disappeared. In the flowing air with a slight fragrance of wood leaves, only intermittent flutes hover in low circles, and all the elapsed time seems to suddenly fluctuate between the fingers of the piper.
This is beautiful and moving music ... TaBaFeng froze again. ...
It's that flute again.

1***
Refers to the simultaneous occurrence of multiple overtones (frequency doubling overtones) of Xiao sound, which controls the depth (strength) change of overtones.
Bass is called "fog sound"
The treble is called "underwater sound"
There is no * * * called pure tone.

The eagle struck Xiao Yang.
Excuse me, Mr. Wen Song, can you still blow the underwater sound above 1? If so, which sounds should be used?
Wen Song
Every flute is different. Generally, the sound of water is not obvious in the ultra-high range, and its resonance overtone is very small, which is obvious in the gas harmony of the mouthpiece. If you make a flute with high brightness, you can still make the ultra-high pitch have higher harmonics to resonate. The sound of water will appear.
The eagle struck Xiao Yang.
Then only a flute that can play high-pitched overtones can play ultra-high-pitched underwater sounds. Hehe, thank you, Mr. Wen Song!
Bamboo flute is not interested in singing, but human taste is pure joy.
